The relationship with Croya, even Zhu Yu himself is not easy to position.

Neither of them is the master of peace.

Zhu Yu estimated that he had traveled all over the world in his life, and he was completely inconsistent with the traditional lover of Her Royal Highness the Princess.

And Croya is even more different from the traditional European image of princesses and ladies. Except for specific festivals that need to be attended with the royal family, there is no one in the royal family at all other times!

Like Zhu Yu, she is also all over the world, and all kinds of legends and ruins have her.

Neither of them has any plans to get married, and on the surface it looks the same as a dew marriage.

Of course, this is not the case. Croya's mind is not in the relationship between men and women, and the reason why she is with Zhu Yu is because Zhu Yu saved her and the hero saved the beauty...... No matter how strong a woman is, she is still relatively weak compared to a strong man.

However, once she left Zhu Yu, Croya immediately transformed into an independent woman, with her own clear goals and no need for other relationships.

If Zhu Yu can settle down and give Croya a stable marriage, her life may be more stable.

But Zhu Yu couldn't give it, and after learning about Zhu Yu's situation, Croya didn't have much expectation for marriage.

It's better to work your goals while you're young. At least when you're older, you have enough experiences to recall.

This is the relationship between the two parties when Zhu Yu is sitting on the plane.

Of course, it's a bit more complicated. After all, the complexity of human nature is not comparable to those of AI.

The plane landed in Stockholm, and when Zhu Yu got out of the plane, he saw Prince Delton waiting anxiously for him.

Apparently, Delton was very worried about his sister. And he also has great hopes for Zhu Yu.

Zhu Yu took Ran Jie and the three of them off the plane and came to Delton.

The two hurriedly greeted each other, and Zhu Yu asked:

"When did Croya go missing? Is there a specific location? ”

Previously, Delton just called Zhu Yu and told him the news of Croya's disappearance, and Zhu Yu hurried over, before he had time to learn the details.

A week earlier, she had been on an expedition to the Faroe Islands and was said to have discovered a prehistoric human site. Because of some previous experiences, we asked her to stay on the phone with us more than once a day.

But three days ago, she didn't call, so we were in a hurry, and contacted nearby officials to look for her area, but no one was found...... Officials have sent a search team, but nothing has been found. ”

Delton's words made Zhu Yu's face sink.

He was not familiar with the Faroe Islands, only that they were located in Northern Europe, with a small area and a small population, and the place and population were equivalent to a township in the northwest border.

It's just that the base here is a volcanic island, so the terrain will be a little more complicated.

Prehistoric human sites?

Is it reliable?

"Then I'll rush over now." Zhu Yu turned around and prepared to continue on the plane.

"No, no, no, although there is an airport there, you can't go on this plane." Delton stopped Zhu Yu, "You still have to prepare." In addition, we also invited some other professional search and rescue teams to ......"

"I'm not with them." Zhu Yu shook his head and said, "You send me the specific location of her last activity, and I'll take someone to find it myself." ”

Zhu Yu didn't distrust those professional searchers, he didn't want Croya to encounter any danger. After all, anything can happen in the wild.

It was once a volcanic island, and no one dared to say it......

Delton didn't stop Zhu Yu anymore, he sent Croya's final position to Zhu Yu, and Zhu Yu hurriedly took Ran Jie and the others away.

Zhu Yu took Ran Jie and carried simple luggage to the local airport, and took a plane to the Vigel Island Airport in the Faroe Islands, which is the only airport in the Faroe Islands.

Out of the airport, Zhu Yu and the others ran directly to the dock again. The 17 inhabited islands and one uninhabited island in the Faroe Islands are mainly transported by boat.

The location of Kroya's disappearance is on Strammer Island, the largest island in the Faroe Islands, with an area of more than 300 square kilometers. It is also the most populous island in the Faroe Islands, and it should have been developed a long time ago, so how could anyone still be missing here?

Zhu Yu did not rush to the location of Deltonfa to find someone, but first looked for the traces of Croya and her predecessors in Thorshavn, the largest city on the island.

A few hours later, Zhu Yu had a harvest.

Croya came here with a small team, four women and three men. They found local guides, hired cars, and bought equipment. According to the owner of the local field gear shop, the place they plan to visit, in addition to one of the sites identified by Delton, is an abandoned cave by the sea.

Sure enough, there is a windfall if you inquire more.

"Boss, where are we going first?" Ran Jie sat in the car and asked Zhu Yu.

"Let's go to the ruins first and see what clues can be found in the ruins."

The off-road vehicle sprang out with the roar of the engine and went straight to the ruins more than ten kilometers away.

According to previous locals, the site was discovered only recently. According to previous researchers, the Faroe Islands were not inhabited by prehistoric humans.

Far from the mainland, only a few sheep and native animals existed before humans migrated. There are very few resources for wildlife, let alone prehistoric humans.

But some time ago, some field explorers discovered a presumably Stone Age human site on the island.

Although it has not yet been officially recognized, the news has attracted many people who come to explore and trace it.

Croya: They're one of them. Originally, this was just an ordinary exploration task, and it can even be said that the significance of tourism is greater than exploration.

But no one thought that Croya would disappear here.

The island's transportation is not very developed. By the time we got to our destination, the road was gone. The buggy drove into knee-deep grass.

It is located in the northwest of northern Europe, already close to the Arctic Circle, with white snow in the mountains, withered weeds, fewer and fewer traces of human activity, and the occasional wild animal can be seen passing through the grass.

"In terms of geographical coordinates, this should be the place."

Ran Jie parked the off-road vehicle near a rock.

Judging from the traces on the ground, there were many cars parked here, and there were traces of human activity. There were many footprints in the neighborhood, both men and women, some trash that had not been completely picked up, and traces of a campfire burning out.

Zhu Yu opened the Heavenly Eye and soon found the traces of Croya's aura nearby.

This pile of rubble does look similar to an early human settlement. Some of the grinding stone tools were thrown aside. There are also traces of excavations on the ground.

If you look at it from a high altitude, you can find that the direction of this stone pile is relatively neat, and there are traces of artificial piling.

The rocks are overgrown with weeds, some of the stones have been weathered, and the rocks should have been piled up a long time ago.

There are some ash pits underneath the rocky soil, and there are some bone fossils in the soil. Scattered stone tools are scattered around, but there is nothing more to excavate.

There were no signs of a fight nearby. No one was killed or injured here. Croya's footprints eventually disappeared into a car mark.

Zhu Yu was sure that Croya should have left here safely, even if she was missing, her disappearance point was not here.

"Let's go to the cave." Zhu Yu looked at the car marks and found that he was really heading in the direction of the cave that the owner of the equipment store said.

At this time, several more cars arrived.

Seven or eight people got out of the car, and a few of them walked straight to the ruins with instruments in their hands.

A few other people came to Zhu Yu and them.

"Are you also here for Princess Croya?" The one who spoke was a tall man with a handsome appearance, somewhat like the guardian of the pharaoh's undead in the Mummy War.

"Yes, but nothing was found." Given that these people were also here to look for Kroya, although Zhu Yu was in a bad mood, his attitude was quite polite.

After finishing speaking, he got into the car, Ran Jie and the three of them also got in the car, and the off-road vehicle started and prepared to leave.

"People must have been found by us in the end. Don't get your hopes up! The honorarium is ours! Behind the tall man, a small man shouted at the SUV that had started.

The off-road vehicle left, Cao Dalong lowered the window, and pointed a middle finger at the people behind him.

"Captain, where are they going?" The little man didn't care at all about Cao Dalong's provocative behavior, and asked at the tall man.

"I don't know. They didn't stop here, maybe they really found other clues, let's look around first. ”

Under the guidance of Zhu Yu, the off-road vehicle followed the car marks and turned around, pressing a deep mark on the grass.

The pliable weeds slowly bounced back into their original shape as the car drove by.

"This is it!" Zhu Yu said suddenly.

The coordinates here are already close to the cave.

The car prints that Zhu Yu and the others followed had traces of staying here, and then turned around and drove away.

The four of them got out of the car and walked down the hill.

The location is close to the sea, and the cold wind carries a damp and salty smell.

The clothes of the four people are not very thick, but fortunately, after the baptism of aura, the resistance in the face of cold is much stronger than that of ordinary people, and the weakest Cao Dalong can barely keep up.

There are slight footprints that stretch halfway up the mountain. Zhu Yu and the others walked in this direction.

There is no soft soil here, but hard white rock.

Over the years, the rocks have been blown by moist sea breezes, and a white crust of salt has formed on the rocks.

When Zhu Yu and the others came halfway up the mountain, they saw a cave hidden in the rocks.

The entrance to the cave used to be huge, at least four or five meters wide and two or three meters high.

At some point, the entrance to the cave collapsed. Rocks have blocked part of the hole, which is now less than a third of its size.

Zhu Yu's eyes were always open, and he could see that there were not only humans entering and exiting the cave, but also other animals, such as sheep.

There is also the breath of Croya here, and Zhu Yu will not admit it.

"Let's eat something and get ready before we go inside." Zhu Yu didn't bring anyone in immediately. Because in his heavenly vision, at least he didn't see the end of this hole.

There is a lot of room for twists and turns in this cave, and there are many forks, so Zhu Yu thinks that the next step will be a very troublesome exploration process.

Ran Jie and the others immediately took out the convenience food from their backpacks and began to eat.

Zhu Yu took out the weapon from his backpack and distributed it to the other three.

As for the behavior of their boss who can take out a weapon at any time, several other people are no longer surprised.

Each of the three took the pistol, checked the bolt, pressed the bullet, and loaded it on his body.

After eating, everyone reorganizes their gear to make sure they get the best result – the backpack fits snugly and the clothes are tight enough to interfere with movement.

Then Ran Jie took the lead, after Qin Fei broke off, Zhu Yu and Cao Dalong were in the middle, and the four of them went to the cave.

The cave first went straight forward, extending for about 20 meters, and then branching out diagonally downwards into two forks.

Walking out of the hole for more than ten meters, the light in front of him had already dimmed, and Ran Jie, who was the first, took out the prepared strong flashlight, and vigilantly illuminated the shadow position as he walked.

The cave was quiet and there was not a single trace of the presence of any creatures. But Zhu Yu's nose was very sensitive, and he faintly smelled some stench.

"Boss, do we need to go our separate ways?"

"No, the four of us will act in unison." Zhu Yu felt that there was an inexplicable danger in this cave, he shook his head and said to go to the left first.

The left side feels a little more dangerous for Zhu Yu.

Knowing that there are tigers in the mountains, he prefers to go to the tiger mountains. If the left side is more dangerous, then the missing Kroya is also more likely to be on the left.

Because there is no trace of Kroya in this area. Zhu Yu couldn't guess why Croya's traces disappeared out of thin air. But in any case, we have to search this cave to the end.

After walking down for more than twenty meters, Zhu Yu and the others felt that the temperature in the cave seemed to have risen a lot.

The walls of the cave are made of limestone, and there are even stalactites from the top of the cave, dripping down the solution drop by drop, and the smell in the air is terrible.

Not long after I walked out, I found another fork in the road.

Still go to the left. Just walk down about fifty meters and the cave will come to an end.

Ran Jie was clinging to the cave wall, and he could hear the rumbling sound inside.

"It's supposed to be an underground river, let's leave it alone." Zhu Yu was a little helpless, no matter how strong the eye is, it also has a range of vision. He couldn't see beforehand that this was a dead end.

Turning back to the fork in the road, they walked to the cave on the right.

The right diagonally turned down and walked out forty or fifty meters, and an underground river appeared in front of it.

The underground river is only seven or eight meters wide, and the water is very muddy. Zhu Yu's gaze sat on the stone wall on the other side of the river.

There is a stone crack in the stone wall. In Zhu Yu's heavenly eyes, there were traces of people passing through this stone crack.

The crack in the stone was barely enough for a person to go sideways, Zhu Yu pointed to the location, and then took the lead and stepped into the underground river.

The deepest position of the underground river is to the waist, and after Zhu Yu lifted his backpack to cross the river, he touched towards the stone crack. Ran Jie and a few people immediately followed, he rushed to Zhu Yu first, and was the first to squeeze into the stone crack.

Zhu Yu was the second to enter, then Cao Dalong, and finally Qin Fei.

The stone slit is not wide, and the backpack can barely get through.

And there was a very unpleasant smell in the crack in the stone.

Zhu Yu found that there was still some dried slime on the stone wall.

This gave him some bad associations.

The stone crack was about more than twenty meters long, and it was already ten minutes before Zhu Yu and the others had completely passed through.

On the opposite side of the stone crack is a large space, the size of a basketball court. The ground is also about three meters high from the roof of the cave.

The smell here is even more unpleasant. Zhu Yu's face changed: he smelled fishy smell, corpse stench and some other inexplicable smells.

Ran Jie and the others also smelled this, and the four of them all clenched the guns in their hands and slowly touched towards the exit of this space.

It's more like a hall, and the exit of the hall is on the right side of the stone crack. In Zhu Yu's field of vision, there were human footprints on the ground, as well as the footprints of some non-human creatures.

The marks left by the opening of those five fingers made Zhu Yu feel a bit like the grunt in the Lord of the Rings.

There was still no light, and after exiting the hall, there was a cave-like environment that led in all directions.

Under the light in Ran Jie's hand, some parts of the cave wall were faintly reflective. There are a lot of rough gemstones set on it.

It's not surprising to think that this was once a volcanic island.

However, now is obviously not the time to hunt for treasures, Zhu Yu just glanced at it, and immediately followed Ran Jie in front of him, and Tianyan looked deeper.

Suddenly, in the field of vision of Tianyan, a black shadow flashed!

To Zhu Yu's surprise, the black shadow actually crawled and disappeared on the top of the cave - this thing has a head and limbs, but there is no hair on the head, and the limbs are slender, because the movement is too fast, Zhu Yu does not see what "he" looks like.

But it's obviously not like the master of Anfen!

"Ran Jie, be careful! There's an unknown creature ahead! Zhu Yu hurriedly reminded him, and then walked quickly to Ran Jie's side.

Qin Fei and Cao Dalong also immediately raised their guns and followed, observing the surroundings.

Although there is no light here, Zhu Yu himself can see secretly, and the night vision of Ran Jie and the others is much stronger than that of ordinary people.

So after Ran Jie turned off the flashlight, the eyesight of several people was only affected to a certain extent, but they could still see clearly in general.

As far as the eye could see, there were no living things.

"Keep going!" Zhu Yu said in a deep voice, "Ran in—by the way, they're on your head, be careful!" ”

As soon as they heard that it was on their heads, Ran Jie and the three of them were shocked.

The first thing they are wary of is what is in front of them, or even what is below them - if something comes overhead, it's really hard to guard against!

After a few turns forward, the front became narrower, but the top was much more spacious.

This abnormal terrain also made them more vigilant!

Suddenly, two black shadows quickly rushed over from the top of the cave in the distance, and only a moment came to Zhu Yu and them!

"Be careful!" Zhu Yu had already shouted when he found the movement in the eye of heaven, and only three or five seconds after he shouted, the two black shadows had already rushed to the top of his head, and stretched out their long claws to grab Qin Fei and Cao Dalong on both sides!

"Bang bang bang!"

Four people shot almost at the same time!
